FastExecuteDataSpecification

@MustBeClosed
public FastExecuteDataSpecification(Machine machine,
 List<Gather> gatherers,
 File reportDir,

Create an instance of this class.

Parameters:

machine - The SpiNNaker machine description.

gatherers - The description of where the gatherers and monitors are.

reportDir - Where to write reports, or null if no reports are to be written.

db - The DSE Database.

Throws:

IOException - If IO goes wrong.

InterruptedException - If communications are interrupted.

URISyntaxException - If the proxy URI is provided but not valid.

StorageException - If there is an error reading the database.

SpinnmanException - If there is an error creating the transceiver.

IllegalStateException - If something really strange occurs with talking to the BMP; this constructor should not be doing that!

Method Details

close

public void close()
           throws IOException

Throws:

IOException

loadCores

public void loadCores(List<Gather> gatherers)
               throws StorageException,
IOException,
ProcessException,
InterruptedException

Execute all application data specifications that a particular connection knows about, storing back in the database the information collected about those executions. Data is transferred using the Fast Data In protocol.

Cannot load data for system cores; those are used by the implementation of this protocol.

Parameters:

gatherers - The receivers of data from the machine.

Throws:

StorageException - If the database can't be talked to.

IOException - If the transceiver can't talk to its sockets.

ProcessException - If SpiNNaker rejects a message.

InterruptedException - If communications are interrupted.

IllegalStateException - If an unexpected exception occurs in any of the parallel tasks.
